Prevention of Significant Deterioration (PSD) and Nonattainment 
New Source Review (NSR): Reconsideration of Inclusion of Fugitive 
Emissions; Interim Rule; Stay and Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Interim rule; stay and revisions.

-----------------------------------------------------------------------

SUMMARY: EPA is taking an interim action to effectuate and extend a 
stay of the final rule entitled ``Prevention of Significant 
Deterioration (PSD) and Nonattainment New Source Review (NSR): 
Reconsideration of Inclusion of Fugitive Emissions'' (``Fugitive 
Emissions Rule'') published in the Federal Register on December 19, 
2008. The Fugitive Emissions Rule under the Federal NSR program 
required that fugitive emissions be included in determining whether a 
physical or operational change results in a major modification only for 
sources in designated industries. EPA issued a stay of the Fugitive 
Emissions Rule on March 31, 2010, that was effective for 18 months 
through October 3, 2011. This action supersedes the stay and thereby 
corrects potential confusion caused by that stay. To effectuate a stay 
of the Fugitive Emissions Rule, this action clarifies the stay and the 
revisions of specific paragraphs in the NSR regulations that were 
affected by the Fugitive Emissions Rule. This action also extends the 
stay until EPA completes its reconsideration of the Fugitive Emissions 
Rule.

DATES: Effective date: This interim rule is effective March 30, 2011.
    The administrative stay of provisions in 40 CFR 51.165, 51.166, 
Appendix S to part 51, and 40 CFR 52.21 published on March 31, 2010 (75 
FR 16012) is lifted; and
    The following Code of Federal Regulations sections are stayed 
indefinitely: 40 CFR 51.165(a)(1)(v)(G) and (a)(1)(vi)(C)(3); 
51.166(b)(2)(v) and (b)(3)(iii)(d); Appendix S to Part 51, Paragraph 
II.A.5(vii); and 52.21(b)(2)(v) and (b)(3)(iii)(c). The EPA will 
publish a document in the Federal Register lifting this stay.
    Comment date: Comments must be received on or before April 29, 
2011.

II. Background Information

    On December 19, 2008, EPA (``we'') issued a final rule revising the 
requirements of the major NSR programs regarding the treatment of 
fugitive emissions (``Fugitive Emissions Rule'') 73 FR 77882. The final 
rule required fugitive emissions to be included in determining whether 
a physical or operational change results in a major modification only 
for sources in industries that have been designated through rulemaking 
under section 302(j) of the Clean Air Act (Act or CAA). Previously, EPA 
rules required that fugitive emissions be included in major 
modification applicability determinations for all source categories. 
The final rule amended all portions of the major NSR program 
regulations: Permit requirements, the PSD program, and the emission 
offset interpretive ruling.
    On February 17, 2009, the Natural Resources Defense Council (NRDC) 
submitted a petition for reconsideration of the December 2008 final 
rule as provided for in CAA 307(d)(7)(B).\1\
---------------------------------------------------------------------------

    \1\ John Walke, NRDC, EPA-HQ-OAR-2004-0014-0060.
---------------------------------------------------------------------------

    On April 24, 2009, we responded to the February 17, 2009, petition 
by letter indicating that we were convening a reconsideration 
proceeding for the December 2008 rule on inclusion of fugitive 
emissions challenged in the petition and granting a 3-month 
administrative stay of the rule contained in the federal NSR program at 
40 CFR parts 51 and 52. The letter also indicated that we would publish 
a notice of proposed rulemaking ``in the near future'' to address the 
specific issues for which we were granting reconsideration.\2\
---------------------------------------------------------------------------

    \2\ Lisa Jackson, US EPA, EPA-HQ-OAR-2004-0014-0062.
---------------------------------------------------------------------------

    The initial 3-month administrative stay of the Fugitive Emissions 
Rule became effective on September 30, 2009. See 74 FR 50115. An 
interim final rule extending the stay for an additional 3 months became 
effective on December 31, 2009. See 74 FR 65692. An additional 18 month 
stay was finalized on March 31, 2010, and ends on October 3, 2011. See 
75 FR 16012. That stay was put in place to allow sufficient time for 
EPA to propose, take public comment on, and issue a final action 
concerning the inclusion of fugitive emissions in the Federal NSR 
program.

III. This Action

A. Why is EPA staying, reinstating, or revising, as appropriate, the 
regulatory text in specific paragraphs affected by the Fugitive 
Emissions Rule?

    The initial stay of the Fugitive Emissions Rule, put in place on 
September 30, 2009, may have caused confusion as to the scope of the 
stay. In staying the Fugitive Emissions Rule, EPA reinstated the NSR 
regulations as they existed prior to the Fugitive Emissions Rule. In 
particular, we stated: ``To effectuate this stay of the December 19, 
2008, rule, we are reinstating previous provisions on a temporary 
basis.'' See 74 FR at 50115-16. In several cases, however, paragraphs 
of the affected regulations in 40 CFR 51.165, 40 CFR 51.166, 40 CFR 51 
Appendix S, and 40 CFR 52.21 appeared to be stayed in their entirety 
rather than amended to undo the changes made by the Fugitive Emissions 
Rule as intended. The subsequent extensions of the stay used the same 
terms as the stay published on September 30, 2009, and accordingly did 
not correct the ambiguity created by the original promulgation of the 
stay. This action clarifies the regulations to accurately reflect EPA's 
intent to revert back to the regulation text that existed prior to the 
Fugitive Emissions Rule amendments to the Federal NSR regulations.

B. Why is EPA issuing an interim rule?

    We are issuing an interim rule to effectuate a stay of the Fugitive 
Emissions Rule. This interim rule supersedes the stay issued on March 
31, 2010, and thereby corrects ambiguity contained in that stay. EPA is 
using the ``good cause'' exemption under the Administrative Procedure 
Act (APA) to take the actions set forth in this interim rule without 
prior notice and comment. See 5 U.S.C. 553(b)(3)(B). Section 553(b)

[[Page 17551]]

of the APA generally requires that any rule to which it applies be 
issued only after the public has received notice of, and had an 
opportunity to comment on, the proposed rule. However, section 
553(b)(3)(B) exempts from those requirements any rule for which the 
issuing agency for good cause finds that providing prior notice and 
comment would be impracticable, unnecessary, or contrary to the public 
interest. Thus, any rule for which EPA makes such a finding is exempt 
from the notice and comment requirements of section 553(b).
    We believe that the circumstances here provide good cause to take 
the actions set forth in this interim rule without prior notice and 
comment, because providing prior notice and comment would be 
unnecessary and contrary to the public interest.
    With this action, EPA is simply staying the provisions of the 
Fugitive Emissions Rule consistent with our original intent, which we 
believe was broadly understood. We believe that soliciting public 
comment on this interim rule prior to making it effective would be 
contrary to the public interest because it is in the public interest to 
correct the ambiguity contained in the current stay as expeditiously as 
possible to avoid potential confusion regarding the regulatory text. 
The NSR program is a vital component of the Act's regime for protecting 
public health, and it is in the public's interest that the requirements 
of the program be clear and unambiguous.
    EPA is also using the APA's good cause exception to make this 
interim rule immediately effective. See 5 U.S.C. 553(d)(3). Section 
553(d) of the APA generally provides that rules may not take effect 
earlier than 30 days after they are published in the Federal Register. 
However, section 553(d)(3) provides that if the issuing agency has made 
a finding of good cause and has published its reasoning with the rule, 
the rule may take effect earlier. EPA has determined that good cause 
exists to stay, reinstate, and revise, as appropriate, certain 
paragraphs in 40 CFR parts 51 and 52 by interim rule without prior 
notice and comment, because prior notice and comment would be 
unnecessary and contrary to the public interest for the reasons stated 
above. Based on this determination, EPA is making this interim rule 
effective immediately.
    Notwithstanding EPA's ``good cause'' finding, we are providing a 
30-day public comment period for this interim rule, and upon reviewing 
and considering comments received, we will issue a final rule either 
affirming the interim rule or affirming the interim rule with 
revisions.

C. What specific revisions are being made?

    We are issuing this interim rule to:
     Stay the following paragraphs: 40 CFR 51.165(a)(1)(v)(G) 
and (a)(1)(vi)(C)(3), 40 CFR 51.166(b)(2)(v) and (b)(3)(iii)(d), 40 CFR 
51 Appendix S II.A.5(vii), and 40 CFR 52.21 (b)(2)(v) and 
(b)(3)(iii)(c);
     Reinstate the following paragraphs: 40 CFR 51.165(a)(4), 
40 CFR 51.166(i)(1)(ii), 40 CFR 51 Appendix S II.F, and 40 CFR 
52.21(i)(1)(vii); and
     Revise the following paragraphs to revert back to the 
regulatory text that existed prior to the Fugitive Emissions Rule 
amendments: 40 CFR 51.165(a)(1)(ix), (a)(1)(xxviii)(B)(2), 
(a)(1)(xxviii)(B)(4), (a)(1)(xxxv)(A)(1), (a)(1)(xxxv)(B)(1), 
(a)(1)(xxxv)(C), (a)(1)(xxxv)(D), (a)(2)(ii)(B), (a)(6)(iii), 
(a)(6)(iv), and (f)(4)(i)(D); 40 CFR 51.166(a)(7)(iv)(b), 
(b)(3)(iii)(c), (b)(20), (b)(40)(ii)(b), (b)(40)(ii)(d), (b)(47)(i)(a), 
(b)(47)(ii)(a), (b)(47)(iii), (b)(47)(iv), (r)(6)(iii), (r)(6)(iv), and 
(w)(4)(i)(d); 40 CFR 51 Appendix S II.A.6(iii), II.A.9, II.A.24(ii)(b), 
II.A.24(ii)(d), II.A.30(i)(a), II.A.30(ii)(a), II.A.30(iii), 
II.A.30(iv), IV.I.1(ii), IV.J.3, IV.J.4, and IV.K.4(i)(d); and 40 CFR 
52.21(a)(2)(iv)(b), (b)(3)(iii)(b), (b)(20), (b)(41)(ii)(b), 
(b)(41)(ii)(d), (b)(48)(i)(a), (b)(48)(ii)(a), (b)(48)(iii), 
(b)(48)(iv), (r)(6)(iii), (r)(6)(iv), and (aa)(4)(i)(d).
    The overall effect of this action is to revert the treatment of 
fugitive emissions in applicability determinations to the approach that 
applied prior to the Fugitive Emissions Rule on an interim basis, while 
EPA completes the reconsideration.

IV. Fugitive Emissions Rule Reconsideration

    Following the public comment period, EPA will issue a final rule 
either affirming the interim rule or affirming the interim rule with 
changes. The final rule will be in effect until EPA completes its 
reconsideration of the Fugitive Emissions Rule. We intend to propose 
and finalize a rule based on the results of the reconsideration by 
October 4, 2012.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under 
Executive Order (EO) 12866 (58 FR 51735, October 4, 1993), because it 
does not raise novel legal or policy issues. Accordingly, this action 
is not subject to review under EO 12866.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden 
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et 
seq. Burden is defined at 5 CFR 1320.3(b). This action only corrects 
inadvertent errors in the existing stay of the regulations at 40 CFR 
parts 51 and 52 concerning the inclusion of fugitive emissions and 
further stays the regulations until EPA completes its reconsideration.
    The Office of Management and Budget (OMB) has previously approved 
the information collection requirements contained in the existing 
regulations (40 CFR parts 51 and 52) under the provisions of the 
Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and has assigned OMB 
control number 2060-0003. The OMB control numbers for EPA's regulations 
in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    This interim rule is not subject to the Regulatory Flexibility Act 
(RFA), which generally requires an agency to prepare a regulatory 
flexibility analysis for any rule that will have a significant economic 
impact on a substantial number of small entities. The RFA applies only 
to rules subject to notice and comment rulemaking requirements under 
the APA or any other statute. This rule is not subject to notice and 
comment requirements under the APA or any other statute because, 
although the rule is subject to the APA, the Agency has invoked the 
``good cause'' exemption under 5 U.S.C. 553(b), therefore it is not 
subject to the notice and comment requirement.

D. Unfunded Mandates Reform Act

    This action contains no federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for state, local, or tribal governments or the private 
sector. This action only corrects inadvertent errors in the existing 
stay of the regulations at 40 CFR parts 51 and 52 concerning the 
inclusion of fugitive emissions and further stays the regulations until 
EPA completes its reconsideration. Therefore, this action is not 
subject to the requirements of sections 202 or 205 of UMRA.
    This action is also not subject to the requirements of section 203 
of UMRA because it contains no regulatory requirements that might 
significantly or uniquely affect small governments.

[[Page 17552]]

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in EO 13132. This action only corrects inadvertent errors in 
the existing stay of the regulations at 40 CFR parts 51 and 52 
concerning the inclusion of fugitive emissions and further stays the 
regulations until EPA completes its reconsideration. Thus, EO 13132 
does not apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications, as specified in EO 
13175 (65 FR 67249, November 9, 2000). This action will not impose any 
new obligations or enforceable duties on tribal governments. Thus, EO 
13175 does not apply to this action.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying 
only to those regulatory actions that concern health or safety risks, 
such that the analysis required under section 5-501 of the EO has the 
potential to influence the regulation. This action is not subject to EO 
13045 because it does not establish an environmental standard intended 
to mitigate health or safety risks.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to EO 13211 (66 FR 28355, May 22, 2001), 
because it is not a significant regulatory action under Executive Order 
12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    This action does not involve technical standards. Therefore, EPA 
did not consider the use of any voluntary consensus standards.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, Feb. 16, 1994) establishes 
Federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA has determined that this interim rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low income populations because it only corrects 
inadvertent errors in the existing stay of the regulations at 40 CFR 
parts 51 and 52 concerning the inclusion of fugitive emissions and 
further stays the regulations until EPA completes its reconsideration.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801, et seq., as added by 
the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect, the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and to the Comptroller 
General of the United States. Section 808 allows the issuing agency to 
make a rule effective sooner than otherwise provided by the CRA if the 
agency makes a good cause finding that notice and public procedure is 
impracticable, unnecessary, or contrary to the public interest. This 
determination must be supported by a brief statement, 5 U.S.C. 808(2). 
As stated previously, EPA has made such a good cause finding, including 
the reasons therefore, and established an effective date of March 30, 
2011. EPA will submit a report containing this rule and other required 
information to the United States Senate, the United States House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. This action is not 
a ``major rule'' as defined by 5 U.S.C. 804(2).

VI. Statutory Authority

    The statutory authority for this action is provided by section 
301(a) of the CAA as amended (42 U.S.C. 7601(a)).

increase will occur at the major stationary source (i.e., the second 
step of the process) is contained in the definition in paragraph 
II.A.6 of this Ruling. Regardless of any such preconstruction 
projections, a major modification results if the project causes a 
significant emissions increase and a significant net emissions 
increase.

Sec.  52.21  Prevention of significant deterioration of air quality.

    (a) * * *
    (2) * * *
    (iv) * * *
    (b) The procedure for calculating (before beginning actual 
construction) whether a significant emissions increase (i.e., the first 
step of the process) will occur depends upon the type of emissions 
units being modified, according to paragraphs (a)(2)(iv)(c) through (f) 
of this section. The procedure for calculating (before

[[Page 17556]]

beginning actual construction) whether a significant net emissions 
increase will occur at the major stationary source (i.e., the second 
step of the process) is contained in the definition in paragraph (b)(3) 
of this section. Regardless of any such preconstruction projections, a 
major modification results if the project causes a significant 
emissions increase and a significant net emissions increase.
* * * * *
    (b) * * *
    (3) * * *
    (iii) * * *
    (b) The increase or decrease in emissions did not occur at a Clean 
Unit except as provided in paragraphs (x)(8) and (y)(10) of this 
section.
* * * * *
    (20) Fugitive emissions means those emissions which could not 
reasonably pass through a stack, chimney, vent, or other functionally 
equivalent opening.
* * * * *
    (41) * * *
    (ii) * * *
    (b) Shall include fugitive emissions to the extent quantifiable, 
and emissions associated with startups, shutdowns, and malfunctions; 
and
* * * * *
    (d) In lieu of using the method set out in paragraphs 
(a)(41)(ii)(a) through (c) of this section, may elect to use the 
emissions unit's potential to emit, in tons per year, as defined under 
paragraph (b)(4) of this section.
* * * * *
    (48) * * *
    (i) * * *
    (a) The average rate shall include fugitive emissions to the extent 
quantifiable, and emissions associated with startups, shutdowns, and 
malfunctions.
* * * * *
    (ii) * * *
    (a) The average rate shall include fugitive emissions to the extent 
quantifiable, and emissions associated with startups, shutdowns, and 
malfunctions.
* * * * *
    (iii) For a new emissions unit, the baseline actual emissions for 
purposes of determining the emissions increase that will result from 
the initial construction and operation of such unit shall equal zero; 
and thereafter, for all other purposes, shall equal the unit's 
potential to emit.
    (iv) For a PAL for a stationary source, the baseline actual 
emissions shall be calculated for existing electric utility steam 
generating units in accordance with the procedures contained in 
paragraph (b)(48)(i) of this section, for other existing emissions 
units in accordance with the procedures contained in paragraph 
(b)(48)(ii) of this section, and for a new emissions unit in accordance 
with the procedures contained in paragraph (b)(48)(iii) of this 
section.

    (i) * * *
    (1) * * *
    (vii) The source or modification would be a major stationary source 
or major modification only if fugitive emissions, to the extent 
quantifiable, are considered in calculating the potential to emit of 
the stationary source or modification and the source does not belong to 
any of the following categories:
    (a) Coal cleaning plants (with thermal dryers);
    (b) Kraft pulp mills;
    (c) Portland cement plants;
    (d) Primary zinc smelters;
    (e) Iron and steel mills;
    (f) Primary aluminum ore reduction plants;
    (g) Primary copper smelters;
    (h) Municipal incinerators capable of charging more than 250 tons 
of refuse per day;
    (i) Hydrofluoric, sulfuric, or nitric acid plants;
    (j) Petroleum refineries;
    (k) Lime plants;
    (l) Phosphate rock processing plants;
    (m) Coke oven batteries;
    (n) Sulfur recovery plants;
    (o) Carbon black plants (furnace process);
    (p) Primary lead smelters;
    (q) Fuel conversion plants;
    (r) Sintering plants;
    (s) Secondary metal production plants;
    (t) Chemical process plants--The term chemical processing plant 
shall not include ethanol production facilities that produce ethanol by 
natural fermentation included in NAICS codes 325193 or 312140;
    (u) Fossil-fuel boilers (or combination thereof) totaling more than 
250 million British thermal units per hour heat input;
    (v) Petroleum storage and transfer units with a total storage 
capacity exceeding 300,000 barrels;
    (w) Taconite ore processing plants;
    (x) Glass fiber processing plants;
    (y) Charcoal production plants;
    (z) Fossil fuel-fired steam electric plants of more than 250 
million British thermal units per hour heat input;
    (aa) Any other stationary source category which, as of August 7, 
1980, is being regulated under section 111 or 112 of the Act; or
* * * * *
    (r) * * *
    (6) * * *
    (iii) The owner or operator shall monitor the emissions of any 
regulated NSR pollutant that could increase as a result of the project 
and that is emitted by any emissions unit identified in paragraph 
(r)(6)(i)(b) of this section; and calculate and maintain a record of 
the annual emissions, in tons per year on a calendar year basis, for a 
period of 5 years following resumption of regular operations after the 
change, or for a period of 10 years following resumption of regular 
operations after the change if the project increases the design 
capacity or potential to emit that regulated NSR pollutant at such 
emissions unit.
    (iv) If the unit is an existing electric utility steam generating 
unit, the owner or operator shall submit a report to the Administrator 
within 60 days after the end of each year during which records must be 
generated under paragraph (r)(6)(iii) of this section setting out the 
unit's annual emissions during the calendar year that preceded 
submission of the report.
* * * * *
    (aa) * * *
    (4) * * *
    (i) * * *
    (d) The PAL shall include fugitive emissions, to the extent 
quantifiable, from all emissions units that emit or have the potential 
to emit the PAL pollutant at the major stationary source.
